Imagine we choose an American household at random and define the random variable C to be the
number of cars (including SUVs and light trucks) the household owns. The standard deviation of C
is 1.08. Which of the following is the best interpretation of this value?
A) The number of cars would be at most 1.08 from the mean.
B) The mean number of cars would be about 1.08 from the expected value.
C) The mean number of cars would be around 1.08
D) The number of cars would be within 1.08 from the mean about 65% of the time.
E) The number of cars would typically be about 1.08 from the mean.
